General Requirements

Product Choice

The aim is to develop a Premium DIY FDM 3d printer for the DIY 3d printer community

• Safety features must be very high
• Fully automated bed leveling
• Engineered advanced Z lift with kinematic coupling
• Integrated dry-box filament container
• We want to be able to print high temp materials
• The project will be open source
• Size should be scalable < 500
• Standard alu profiles. 2040 and 2020
• Belted Z drive
• Advanced Firmware options
• Enclosed chamber with engineered insulation for <80C Chamber temp

Function Choices

The machine should have all the functions needed for a trouble-free user experience. The goal is to implement all basic functions plus any feature that is making an advanced high temp premium 3d printer
